AS/NZS 1802 Type 275 1.1 kV Shuttle Car Cable – Heavy Duty Flexible Mining Reeling Cable for Underground Mobile Equipment

Overview

AS/NZS 1802 Type 275 1.1 kV shuttle car cable is a heavy-duty flexible mining cable specifically engineered for high-speed reeling applications used on underground shuttle cars and other mobile mining equipment. Designed to withstand extreme mechanical stress, torsional movement, repeated flexing, and harsh underground operating environments, this cable construction provides excellent resistance to “corkscrewing” during continuous operation.

Manufactured in accordance with AS/NZS 1802 requirements, Type 275 cables are widely used in underground coal mines, hard rock mining operations, and heavy-duty material handling systems where reliable power transmission and mechanical durability are essential.
